ABSTRACT
An investigation into the impact on CISCO Quality of Service (QoS) during a Distributed Denial ofService attack (DDoS). Several different QoS modes were tested. Two key factors were of interest: (1) Resistance to attack degradation, and (2) The ability to reserve enough bandwidth to enablefuture in-band control and reconfiguration messages. The results show that performance is highly dependent on both the QoS modes used and the selected data protocols.
